| To EY. From Hs {Lord Ernest Hives - Chair} /Rn. {Mr Robinson} X4308 Hs {Lord Ernest Hives - Chair} /Ru2/LG1 5. 8. 28. SPEEDOMETER GEAR RATIOS. X 4308 X 5310 On Mr. Royce's car the mileage recorder reads 3% fast. As we propose to fit small instruments to both the two IndiaIndia chassis we are at present manufacturing, we think it is worth while altering the speedometer drive ratio in the gearbox by 3% on these two chassis so that we can get the correct speedometer to be used on all cars when the 19" rim comes on production. We attach a letter from Messrs. A.T. which explains the situation. Hs {Lord Ernest Hives - Chair} /Rn. {Mr Robinson} | ||
